I have a patient who had 3 implants installed in the maxillary arch and 6 implants installed in the mandibular arch. Three implants in the maxillary arch were not given healing caps. One implant in the mandibular arch does not not have a healing cap. Is it critical for the healing process to have the internal surface of the implant sealed with a healing cap? It is now ten days after the operation, is it too late to put healing caps on? Should I just leave as is and onserve the healing?
